Spectral data for biopolymer solution in water and cell-free supernatant are used to build PLS models. Four variable selection algorithm, i.e., GA, CARS, ABUSE, and PSO are adopted to build PLS sub-mo
SC: spectral count. TMT: tandem mass tag. Proteins verified by western blot analysis are indicated in italic. WB on crude plasma samples1. WB on depleted plasma samples2. ND: non detected. NC: non cal
